Description
Lanthanum -Tungsten Electrode is well known for its good welding performance. It is the electrode added with 1-2% of La2O3. The power of its electronic transgression is 2.7-2.8EV, bearing the closest features to those of the Thorium-Tungsten Electrode. Its arc features and burn spoilage endurance used with small and medium currents.
Lanthanum-Tungsten Electrode is the substitution product of thorium-tungsten electrode because of its non-radiation. Its other advantage is its endurance of high current and low burn spoilage rate.
